Which task is NOT age-appropriate for a 14-15 year old?

Operating an agricultural tractor typically requires a higher level of responsibility and understanding of safety protocols compared to the other tasks listed. This is due to the complex machinery involved, which can present significant risks if not operated correctly. Agricultural tractors not only have more power and size but also involve a greater awareness of surroundings, attachment usage, and operational knowledge that may not be fully grasped by younger teens.

In contrast, operating a lawn mower, working in a garden, and harvesting crops are generally considered more accessible tasks for 14-15 year-olds. These activities often involve simpler equipment and lower stakes in terms of safety risk. While all tasks require some level of instruction and caution, operating an agricultural tractor is often regulated more strictly and may require formal training or certification due to its implications for safety in agricultural environments.
